Working pressures can range from 2250 PSI for low pressure steel tanks to 3440 PSI for high pressure steel tanks.

One is that the extra aluminum makes the tanks heavier. … Most are around two and a half feet long and weigh about 26 to 40 pounds, but the largest tanks are even bigger and heavier than this. A larger tank will also have greater air capacity, letting divers have longer bottom times.
